title: Atrioventricular and interventricular groove and septal extension of right sinus of valsalva aneurysm: a rare cause of complete heart block.
abstract: A 26 years old male presented with vertigo and history of fall. The electrocardiogram revealed 2:1 second-degree heart block and later progression to complete heart block. Transthoracic echocardiography revealed aneurysm at the site of ascending aorta and computed tomographic scan showed an aneurysm of right sinsus of Valsalva extending into right atrioventricular and interventricular groove and causing complete heart block by compression on the conduction system. He also suffered from lymph node tuberculosis. This case report is unique because of rare presentation as complete heart block.
